152 ITU‐T's Technical Reports and Specifications Smart Healthcare Management: These management systems can convert health related data into clinical and business insights, and enable secure communications and information sharing in order to improve the productivity of the service provided to citizens. Examples of smart healthcare systems include the availability and improvement of remote diagnosis, remote treatment, on‐line medical services, health management systems and remote patient monitoring systems. To achieve these goals, M2M communications will be crucial. Smart Education: Education, for adults and children, may be the most important smart city service. The use of ICT can improve education by providing the student with a personalized learning environment (e.g., tailored to his progression level, interests, learning style), as well as by providing educators with new tools to design learning activities or opening new communication channels with student, parents and community members. At the city level, the use of ICT in education can generate other economic and social benefits, including the improvement of tourism services. Smart Security: Ensuring physical safety and security required, the use of ICTs responds to the need of resolving incidents, providing criminal identification, as well as conducting predictive analysis and criminal pattern identification to improve the citizen safety. Command and control systems shared across multiple city departments like energy, waste, transport and security will be needed to provide a holistic city‐wide view of safety patterns and trends. New ICT infrastructure also has to be protected from security threats. Smart Buildings Systems: These systems can use data to improve building energy efficiency, reduce wastage and optimize water usage, without affecting the occupants' satisfaction. These systems may include building automation, life safety, and telecommunications, among others. The analysis conducted thus far suggests that ICT use can improve the efficiency of city services and, ultimately, strengthen the quality of life of its citizens. To assess these benefits, Key Performance Indicators (KPIs) are needed to quantify and evaluate the transformation of a city into a smart sustainable city. Other KPIs that are specifically designed for each city service, are also needed to monitor performance and assess, quantitatively, the efficiency gained through the implementation of SSC solutions. While the list of smart services provided earlier reflects the standard/most common city services, municipalities can integrate different services according to their own needs and priorities. b) Key Performance Indicators, Standards. Key Performance Indicators (KPIs) are not only useful to evaluate the performance of city services, but can also be used to assess, empirically, how one or a set of modifications contribute to the city's transformation into a smart sustainable city, providing ground for standardization. KPIs can also allow comparisons between different cities to determine which one is 'smarter' or more sustainable in the face of particular challenges. Evaluating these indicators can help cities as well as their stakeholders understand to what extent they may be perceived as Smart Sustainable Cities (SSC).
